Construct an angle of $157.5^{\circ}$ and write the steps of construction.

(N/A) To construct an angle of $157.5^{\circ}$,we note that $157.5^{\circ} = 180^{\circ} - 22.5^{\circ}$.
$1$. Draw a ray $OA$.
$2$. Construct an angle of $180^{\circ}$ at point $O$ using a protractor or by extending the line.
$3$. Construct an angle of $45^{\circ}$ at point $O$ by bisecting the $90^{\circ}$ angle.
$4$. Bisect the $45^{\circ}$ angle to obtain $22.5^{\circ}$.
$5$. Subtract $22.5^{\circ}$ from $180^{\circ}$ to get $157.5^{\circ}$.
